Landing at the southern Italian city on July 28, the Ottoman force quickly overwhelmed Otranto. (Otranto rashly slew the messenger come to offer a merciful capitulation, only to find that its garrison began deserting within days.) On August 11, the Turks took the city by storm. Thousands died on that day’s bloodbath, including the Archbishop of Otranto.

Surviving women and children were sold into slavery. Men over age 15 had the choice of conversion — or death.

“Now it is time for us to fight to save our souls for the Lord!” a Christian shoemaker is said to have exhorted his 800 fellow prisoners. “And since he died on the cross for us, it is fitting that we should die for him.”

The acclaim greeting this call signaled inflammation ahead for the Turkish headsmen’s rotator cuffs. They had 800 faithful souls to dispatch to their eternal reward this date at the place still known as the Hill of Martyrs. (When in Otranto, visit it by taking the via Ottocento Martiri, just off via Antonio Primaldo — that’s the name of the militant shoemaker.)

This, at least, is the most pious version of the story. The mass execution certainly did occur, but some latter-day historians like Francesco Tateo have argued that martyrdom is not attested by any of the contemporaneous sources, and the specifically religious understanding of events was only read in after the fact.

On whatever grounds one likes, Italy’s fractious city-states were deeply alarmed by the appearance on their shores of the all-conquering Turks. “It will always seem as if the funeral cross is borne before me while these barbarians remain in the boundaries of Italy,” wrote the Florentine humanist Poliziano.* (Source, a nonfiction book which covers Otranto in some detail.)

In the ensuing months, they rallied together vowing to expel the invaders.

Fortunately for this coalition, the Ottoman sultan Mehmed the Conqueror died in May 1481, and a brief period of internal conflict within the Ottoman empire over the succession perhaps led it to allow its Otranto outpost to wither on the vine. The Turks made peace and withdrew from their potential beachhead not long after, having held the city for just over a year. The bodies of the martyrs were said to have been found uncorrupted by decay.

The Catholic church beatified the 800 martyrs in 1771, but their final elevation to sainthood occurred only in 2013, just three months ago as I write this. They were in the very first group canonized by the new Pope Francis — although the canonization was approved by his predecessor Benedict XVI on the same day that Benedict resigned his pontificate. Considering current relations between the respective faiths, it was seen as a potentially impolitic move.

“By venerating the martyrs of Otranto, we ask God to protect the many Christians who in these times, and in many parts of the world, are still victims of violence,” Pope Francis said at the canonization Mass, diplomatically not naming any of those parts of the world.
